Answer:
a) f(6)=(6)^2+4(6)+1=65
b)f (x+9)=(x+9)^2+4 (x+9)+1=(x^2+18x+81)+(4x+36)+1=x^2+22x+117
f (-x)=(-x)^2-4x+1
Itd be 1, because the other ones aren’t possible
129,407 because 12 ten thousands=120,0008 thousands= 8,00014 hundreds= 1,400No tens=07 ones=7
Find out how many times 25 goes into 100, it goes in 4 times so you do 19×4
19×4=76
